IMPROVEMEMT IN MACHINES FOR CHAMFERING BARRELS.

Specification forming part of Letters Patent No. 33,908, dated December10, 1861.

. To all whom it may concern:

Be it known that I, JOHN TILLEY, of the village of lVest Troy, in thecounty of Albany and State of New York, have invented a new and usefulImproved Machine for Chamfering, Leveling, and CrozingBarrels, Kegs, andCasks; and I do hereby declare that the following is a full and exactdescription of my improved machine and invention, reference being had tothe annexed drawings, which make a part ot' this specification, inwhich- Figure l is an end elevation; Fig. 2, ahorizontal section at andplan of parts below the lines z z; and Fig. 3, a side elevation andpartial vertical longitudinal section at the line y y', all of a machinewhich embodies my invention.

The same letters refer to like parts in all the figures, and the arrowstherein indicate the directions in which the part-s are moved.

One part ot' my invention relates to the construction of the apparatusfor clamping and holding the open bulging cylinder of staves or barrel Apreparatory to and during the operation of revolving the barrel indress- I ing its ends, and that part of my'invention consists inconstructing and arranging two circular barrel-holding rings B B looselywithin or upon two annular or open supporting-stocks C C', one or bothof the latter being made suitably movable to readily admit, clamp, andrelease the barrel, so that the said ringsB B shall notonly serve astruss-hoops to squeeze together and firmly hold the ends of the stavesin a circle for the action of the chamfering and other enddressingcutters, but shall also serve as the axles upon and with which thebarrel is revolved and as guides to prevent the barrel from movingeither endwise or sidewise while revolving under the action of thecutters, and so that not only the two ends and the inner surface of thebarrel, but also its outer surface shall be left so uncovered that thebarrel can be properly' revolved by a running belt I or other suitablemeans applied directly to the outer surface of the barrel, and that thechamfering, leveling, and crozing of both ends of the barrel and alsothe smoothing off of most of both the inner and outer surfaces thereofmay all be effected simultaneously or without changing the barrel, allessentially as shown and indicated by the annexed drawings.

In the annexed drawings, D is a horizontal bed-piece on which the twoupright annular or open .stocks O C', which support the two rings B B,are mounted, with the said rings parallel and directly opposite to eachother, and upon which bed-piece D the stock C can be moved toward andfrom the iixed stock C, as indicated by the dotted lines at in Fig. 3,by means of a rack e and lever-pinion g f or their equivalent, so as toallow the cylinder of staves A to be readily clamped by and releasedfrom the said rings. The inner sides of the rings B B', Fig. 2, are madedaring, so that when the staves are set up and held together by twotruss-hoops h h about half-way between the middle andY ends of thebarrel and placed endwise between the rings B B the ends of the bulgingcylinder of staves will enter the flaring side of the ringsas the stockC is moved toward the stock C and will be squeezed together by andpressed through so as to extend somewhat outside of the rings, andthereby held firmly in circular form to receive the action ot' thecutters. The rings B B are respectively secured to and fitted to freelyturn on their axes within or upon the stocks C C in planes substantiallyparallel to each other, so that the rings B B not only form the chucksfor holding the barrel, but also serve as the axles upon which it isrevolved to receive the action ot` the crozing, leveling, and chamferingcutters.

Another part of my invention relates to the manner of arranging` theleveling and chamfering cutters in combination with the apparatus forholding the revolving barrel or open bulging cylinder of staves. Thispart of my invention consists of the arrangement, in combination withthe apparatus for holding the revolving barrel with both its endsuncovered, of two groove-cutting chamferingknives J J and twogroove-cutting levelingknives P P', the knives J J being located withinthe cylinder described by the revolving barrel' and made movable, so asto cut scores or grooves in the barrel from its inner su rface outwardtoward its ends, substantially in the planes of and so as to therebyform the chamters of the barrel, and the knives P P being' placedoutside of the cylinder described by the revolving barrel and mademovable, so as to cut grooves in the barrel from its outer surfaceinward toward its axis, substantially in the planes of and so as tothereby make the leveled ends of the barrel, all essentially as isindicated by the annexed drawings.

1n the annexed drawings, the chamferingknives J J, Fig. 2, are pivotedat Z Z to arms m m, fast on rests n n, fixed to the barrelsupports C C',and have handles o o, by which the person or persons operating themachine can move the knives J J to cut the chamfers Za Za as the barrelis revolved. The leveling-knives P P are pivoted at q q to the stocks CC', and have handles r r', by which the operator or operators can moveeach of those knives to cut a score c, Fig. 5, in the outside of therevolving barrel to level its ends. By this arrangement of thechamfering and leveling knives J J and P P with the barrel-holdingapparatus the excess of wood w, Fig. 5, can be cut off and therebyremoved from both the chamfer and end of the barrel in a mass togetheras the barrel is revolved by simply cutting two scores or groovessubstantially in the direction of and in depth equal to the Width of thechamfer and leveled end of the barrel, respectively, thus avoiding theexpenditure of time and power which is required in some barrel-machinesto cut away that excess of wood in the form of numberless chips orshavings.

In Fig. 2 the cutters J and P are shown in the positions which theknives occupy in respect to the revolving cylinder of staves A just asthe knives finish the chamtering and leveling of the barrel, and in thesame ligure the knives J and P are shown removed from the stavespreparatory to the removal of the finished barrel and the insertion ofan undressed one. The parts m m', to which the knives J J are pivoted,may be made adjustable, so that those knives can be set to cut thechamfers k Zc at different inclinaions, asindicated by dotted lines inFig. 2 at the letters J Zand J Z, and both the chamfering and scoring orleveling cutters J J P P may be made to move, so as to cut off andchamter the ends of the barrel, as above described, in or upon suitableways or guides, instead of upon pivots Z Z and q g', as shown by theannexed drawings.

S S, Fig. 2, are sliding crozing-cutters, and it the handles they areoperated by. The stops u u control the depth of the Crozes. All theseparts are mounted on the stocks C C', which latter may also have movablehoweling-cutters to make even the inner surface of the barrel toward itsends as the barrel is revolved. With all the cutters thus mounted on thestocks C C the barrels will all be crozed and chamtered to one size.

Now I do not broadly claim as new an apparatus for clamping and holdinga revolving barrel or open bulging cylinder of staves with both ends ofthe staves exposed or uncov-Y ered; neither do I claim an arrangement ofmovable chamfering and leveling cutters with both ends of an apparatusfor thus holding a revolving barrel so that thc chamfering and levelingof both ends of the barrel can be thereby elected simultaneously orwithout changing the barrel and so that the excess of wood which isremoved from each end ot' the barrel in leveling its ends shall be cutoit in one mass or Without being all cut into chips or shavings; and Ido not claim the arrangement, in combination with an apparatus forholding a revolving cylindrical body, of two knives mounted to. moveendwise and cut two continuous grooves substantially in the plane ordirection of and thereby form two chamfers on and around the cylindricalbody, as in some machines heretofore made for chamfering the disk-likeheads for barrels. 'In my improved machine the chamfering-knives J J arearranged to move and cut the grooves away from each other, and therebyform the chamfers on the inner surface of the revolving cylinder ofstaves, instead of being arranged to move and cut the grooves towardeach other, and thereby form the chamfers on the outer surface or edgeof a revolving disk or barrel-head; and I do not claim cutting off orleveling the ends of a hollow revolving cylinder by means ot two knivesarranged in combination with an apparatus for holding the revolvingcylinder so that the said knives can be moved to cut scores or groovesin and around the cylinder as it is revolved from its outer side inwardtoward its axis and substantially in the planes of its leveled ends; nordo I claim any part or com` bination or arrangement of parts shown orspecified in Nos. 4,218, 23,097, and 26,206 of United States LettersPatent for inventions. What I claim as new and of my invention, anddesire to secure by Letters Patent, is-

l. The rotary truss-rings B B when constructed and arranged with the endstocks C C', mounted together and one or both made movable, allsubstantially as and for the -pur pose herein set forth.

2. The arrangement of the two groove-cutting chamferng-knives JJ and thetwo scorecutting leveling-knives P P', in combination with the apparatusfor holding the revolving cylinder of staves with both ends of thestaves exposed, as and for the purpose herein set forth.
